Fuse clamp file

ABSTRACT

This device consists primarily of a shank portion or stem, terminating at one end as a curved portion for lifting a fuse of the cartridge type from its clamp and the other end terminates as a cylindrical bar which is serrated so as to remove any corrosion within the clamp by arcuately rotating, the shank portion back and forth.

3 Claims, 2 Drawing Figures FUSE CLAMP FILE This invention relates to fuses in electrical circuits, and more particularly to a fuse clamp file.

It is therefore the principal object of this invention to provide a fuse clamp file which will serve as a means for easily removing a cartridge fuse from its clamp and will serve a dual function as a means of removing any corrosion present within the fuse clamp.

A further object of this invention is to provide a fuse clamp file of the type described, which will consist of a shank portion which is held in the hand of the user, terminating at one end by a curved flat portion which will enable the user to easily engage the cartridge fuse so as to remove it from its clamp and the opposite end of the shank is terminated by a cylindrical bar portion having serrations on the outer peripheral ends, so that the serrations serving as file means for removing corrosion that may be present within the fuse clamp.

Other objects of the invention are to provide a fuse clamp file which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and efficient in operation.

These and other objects will be readily evident upon a study of the following specifications and the accompanying drawing, wherein:

FIG. 1 is a perspective view of the present invention, and

FIG. 2 is a bottom plan view of FIG. 1.

According to this invention, a fuse clamp file 10 is shown to consist of a cylindrical shank 11 and a curved flat portion 12, the opposite end being a cylindrical bar portion 13 having serrations 14 at its outer peripheral ends, the serrations serving as file means for frictionally engaging the clamp on its interior periphial surface so as to remove any corrosion that may be present.

In use, the end portion 12 is engaged with the outer peripheral surface of the cartridge fuse so as to disengage it from its clamp and the shank 11 is reversed so that the cylindrical bar portion 13 that is engaged within the clamp serves to file away any corrosion present in the clamp by moving the cylindrical bar portion in a backwards and forwards motion along its longitudinal axes by minipulation of the shank ll.

It shall be noted that device 10 may be L-shaped in configuration and may have only one serrated end if is desired. I

What I claim is:

1. A fuse clamp file, comprising a shank, a flat end portion carried at one end of said shank for removing a cartridge fuse from its clamp, a transverse bar portion carried by said shank at the other end, said bar providing filing means on opposite sides of said shank for removing possible corrosion within said clamp.

2. The combination according to claim 1, wherein the flat end portion of said shank is arcuately curved from one side of the longitudinal axes of said shank.

3. The combination according to claim 2, wherein said bar portion of said shank is cylindrical and at right angles to the longitudinal axes of said shank and each outer peripheral end is serrated so as to form said file means for removing corrosion from said fuse clamp when said cartridge is removed from said fuse clamp by said arcuately curved end portion of said shank.
